Physicists Develop New Method to Detect Tiny Fluctuations in Spacetime
Physicists at the University of Warwick have developed a new framework to detect tiny spacetime fluctuations known as “quantum foam,” a long-standing prediction of quantum gravity theories. The study maps different types of spacetime noise to measurable signals in interferometers such as LIGO and smaller laboratory setups. By translating abstra...

New Study Explores How LIGO-Style Lasers Could Test Quantum Gravity
Gravitational waves, first directly detected in 2015, have opened a new way of observing the universe. Now, physicist Ralf Schützhold of HZDR proposes going a step further—actively interacting with these ripples in spacetime using powerful lasers. His theoretical scheme builds on LIGO-style interferometers, where intense laser pulses bounce repe...

New Gravitational-Wave Signal May Reveal Primordial Black Holes Born After the Big Bang
Scientists have spotted an unusual gravitational-wave signal that may reveal the universe’s first primordial black holes—tiny relics dating back to the Big Bang. Recorded by LIGO–Virgo–KAGRA in November 2025, the event involves an object far lighter than any known stellar remnant. If verified, it could reshape theories of black holes and da...

Scientists Solve the Mystery Behind LIGO’s “Forbidden” Black Hole Pair
When LIGO and Virgo detected GW231123 in late 2023, it appeared to show two black holes merging in the so-called mass gap, where theory predicted none should exist. But new simulations indicate that rapidly spinning, strongly magnetized massive stars can collapse into black holes without exploding entirely. This process sheds enough mass to leave b...

LIGO Detect Possible Second-Generation Black Holes with Extreme Spins
LIGO-Virgo-KAGRA observatories detected two extraordinary black hole collisions in late 2024—GW241011 and GW241110. The first involved a rapidly spinning black hole, while the second revealed one rotating opposite its orbit. These findings fit predictions for second-generation black holes, born from earlier mergers within crowded star clusters. T...

New Black Hole Merger Gives Clearest Test of Einstein’s Relativity
LIGO has detected GW250114, the loudest gravitational-wave signal yet, marking ten years since its first breakthrough. The event confirmed Einstein’s relativity, Hawking’s horizon theorem, and Kerr’s spinning black hole model. By capturing the merger of two 32-solar-mass black holes, scientists gained the clearest view of black hole physics, ...

Gravitational Waves Reveal Most Massive Black Hole Merger Ever Observed
The GW231123 event marks the most massive black hole merger ever detected through gravitational waves, involving black holes of 100 and 140 solar masses. Observed by the LIGO-Virgo-KAGRA network, it challenges current black hole formation models with extreme mass and spin, suggesting a complex origin. Scientists believe its full implications may ta...

Scientists Detect Biggest Merger Of Two Black Holes In History
Scientists have detected the most massive merger of two black holes ever recorded for the first time in history.

Gravitational Waves Reveal Black Hole Ancestry Through Spin Analysis
A study published in Physical Review Letters explores how gravitational waves reveal the ancestry of black holes. By examining 69 black hole mergers, researchers found that spin shifts indicate repeated collisions in dense star clusters. This insight supports models suggesting black holes grow through sequential mergers. Observatories like LIGO and...

Scientists Develop New Approach to Capture Gravitational Wave Memory from Supernovae
A study published in Physical Review Letters highlights new methods to detect the gravitational wave memory effect, a unique phenomenon predicted by Einstein's general relativity. Core-collapse supernovae (massive stellar explosions) generate these low-frequency gravitational waves, offering a rare glimpse into stellar interiors. Despite their weak...
